Lime calciner paint liner and forming method thereof

Abstract

The invention relates to a lime calciner paint liner and a forming method thereof. The lining comprises a thermal insulation layer, a middle lining layer and a working layer which are sequentially attached to the inner wall of the shell of the lime calciner, wherein the middle lining layer and the working layer are sequentially combined into an integral body and are respectively a paint layer according to a certain formula. The forming method comprises the following steps: thoroughly mixing the raw materials of the paint uniformly, adding into a feed hopper of a pneumatic rotary spray gun, sending the raw materials in the feed hopper into the spray gun by compressed air through a rubber tube, mixing the raw materials with high-pressure water in the spray gun to form a slurry, and spraying the slurry onto a construction working surface layer by layer. The invention provides a novel liner and a forming method thereof for the lime calciner, thereby greatly enhancing the forming efficiency of the lime calciner liner, lowering the production cost, greatly enhancing the quality of the lime calciner liner, and greatly prolonging the service life of the lime calciner liner; and the method can also be efficiently used for repairing local damage of a lime calciner paint liner or refractory cast-forming liner.

Description

technical field [0001] The invention relates to a lining body of a lime calciner composed of a coating layer and a forming method thereof. Background technique [0002] Existing lime calciners for producing quicklime usually consist of a shell and an inner lining. The inner lining is generally composed of a thermal insulation layer, an intermediate lining layer and a working layer. The thermal insulation layer is the outer layer of the inner lining and is connected to the inner wall of the shell. At present, the thermal insulation layer, intermediate lining layer and working layer of the inner lining are basically built on the inner wall of the furnace shell by using different refractory and thermal insulation materials, or adopt different unshaped refractory and thermal insulation materials to pass through The formwork is poured on the inner wall of the furnace shell in turn to form an integral inner lining. However, since the structure of the lime calcination furnace is n...

Problems solved by technology

However, since the structure of the lime calcination furnace is not a regular cylindrical shape, but a vase shape with a large middle and two small ends, the furnace body is divided into a preheating section, a calcination section and a cooling section from bottom to top, so the inner lining is built with shaped bricks. It is cumbersome and difficult to construct or use amorphous refractory and thermal insulation materials through formwork. It is not only time-consuming and labor-intensive, but also has a long construction period, and the construction quality is not easy to guarantee; trouble, difficulty
